I was tired of putting the anchors over
the side and retrieving them with the rode/chain dragging on the boat
and the whole deal getting harder as I was getting older. Also we
tend to use heavier anchors than most and the weight of the 22 lb.
claw and 25 lb. Manson Supreme along with the chain was not easy to
deal with leaning over the side of the boat.

..................

The anchors are different enough that I
wanted one side of the double bow roller (which will be called DBR
for the rest of this) to fit the claw and the other to fit the
Manson, arrows. I started mocking the whole thing up with a piece of
scrap plywood.

..................

I could attach and detach it easy with
the second piece of plywood that I jammed in between the one and the
underside of the side cleats on the bow.

..................

I started with the rollers I bought and
put some side arms on for them and experimented with...

..................

... different lengths out to the rollers
and different locations for the...

..................

.... the rollers until I liked how the
anchors fit/rode and ...

..................

... how easily they would deploy and
retrieve. The double rollers on the end help in the deployment and
retrieving.

..................

Above is the final stage of the wood
prototype.

..................

I started first with the side arms and
marked off some pieces on a sheet of 0.125" 5086 aluminum as it
has has excellent corrosion resistance.

..................

The arms and other pieces were cut.....

..................

.... with a plasma cutter. Here I'm
cutting the additional pieces that will go at the front bottoms of
the arms.

..................

I squared some of the cuts up with the
mill.

..................

Here are the parts that make up the arms.

..................

I drew in the final shape. The dotted
lines are 'fold' lines and the round areas are for bushings for the
rollers.

..................

The pieces were cut our and reinforcing
bushings were made, bottom arrow, for the rollers, top right arrow.

..................

The bends were put in so that the anchor
rode would not wear on the front if we sat on anchor with the rode
left in the roller vs. being moved to a bow side cleat. To make the
bends I had to make a relief cut which...

..................

... was then welded shut, bottom right
arrow. Also the bushings were welded into the pieces at this point.

..................

A finished bottom front arm.

..................

... These pieces were different on the
side for the claw vs. the Manson as the shanks on the two anchors are
not the same.

..................

These posts were then machined next. You
will see later how these add a lot of flexibility...

..................

.. how you can run the rodes depending on
anchoring conditions.

..................

Once the plywood pattern was finalize it
was used to trace the bottom of the bow roller assembly.

..................

The bottom fronts for the arms were now
welded to the tops and finished off on the ends and bottoms.
